"My previous 4mm drill bit (Richmond) got a little bent from heavy use so I thought I would replace it with Dewalt. Got it out the packet and drilled a pilot hole into a 18mm plywood. Snapped on first use in my Makita 18v drill.Cheap Rubbish. Avoid."

"Currently building a deck and after using a single Bosch drill bit for the first 200+ pilot holes it finally went blunt. Bought 5 of these De Walts and they all broke whilst drilling fewer than 50 holes. They are very brittle and prone to snapping. Avoid."
